Abstract (en)
[origin: WO2020035223A1] The invention relates to a connecting device (1) for connecting car bodies of a rail vehicle, the task of which connecting device is to provide improved absorption of energy in the event of a collision. According to the invention, a connecting device (1) is provided, comprising an outer housing (2), an inner housing (3) and an energy absorber (4) connected to the outer housing (2) and to the inner housing (3), which are arranged substantially along a common longitudinal axis. The connecting device (1) furthermore comprises a driving device (13) for connecting the connecting device (1) to a car body housing of a car body. The connecting device (1) is designed to transmit tensile forces and compressive forces along the longitudinal axis. The energy absorber (4) is designed to irreversibly deform if a predetermined pressure force along the longitudinal axis is overshot, such that the length of the connecting device (1) along the longitudinal axis decreases and the inner housing (3) partially slides into the outer housing (2).
